The problem is if you bought any of your firearms with a C&R license then a paper copy is mandatory.
Let's mix things up a little.
Take out your cell phone and take pics of your weapon. Every area of interest. Serial number, who made it, any special marks, etc. NOW print the pics. Then hole punch and put into a binder about the weapon. Add to the binder a page about who you bought from and price and any other details. Now take a pic of the page you wrote on. Download the everything into your computer. You now have a written, printed copy and a copy of everything on your computer. Now make an electronic copy of everything and store in a special place, NOT near your weapon/weapons. Might also want to include dates bought and sold and current value for others if something happens to you.
Lots of good ideas in this thread. If need be, look up what a gun shop owner is required to do and ADD from there,
That said ---- DO IT!! Most of us do NOT have a current complete listing of our stuff, some do. Find and choose a system and go for it.

I also use an Excel spreadsheet, and 3" ring binders with plastic insert holders for all information I come across over time.
My system precisely. Sans purchase date (should have thought of that). I use a link to the photos which it sounds you do as well. Don't forget the dreaded TOTAL INVESTMENT TOTAL at the amount paid column.
I also include a Willed to Column in hopes the new stewards will enjoy them as much as I.
Thank you to all that have replied. I have seen the hard copy books but I want the flexibility of an electronic record, particularly with regards to being able to edit info as others have mentioned. I also don't want to be locked in to using a layout or fields that I don't need. More food for thought!
I do my best to keep mine accurate and up to date, but I also purposely let my license lapse. As soon as it does, I can destroy those records. I then apply for my license again. It doesn't cost any extra, and I have about two months every three years where I don't have a license. But my liability for accurate C&R records only goes back to the start of my most recent license.
